Description

This advisory documents a vulnerability in Arista EOS for security ACL bypass. The issue allows a security ACL drop rule to be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could enable incorrect forwarding of packets that should have been denied by the Security ACL, potentially allowing an ACL bypass. The issue was discovered internally by Arista.
